# Installation Guide | Prepare the Alta X for the EON800 Tether System ## Step A: Install the *EON800* *Serial Port Patch Panel for Alta X* The ***EON800 Serial Port Patch Panel for Alta X*** supplies the connection between the ***EON800 APU*** and the Internal ***Alta X FRX Cable** (JST-GH 6-Pin)*. The ***Alta X FRX Cable*** is alternatively used for an FRX radio and is located inside of the *Alta X chassis*, adjacent to the *GPS/RTK GPS* unit. *Once the **Serial Port Patch Panel*** is installed, we recommend it remains permanently fixed to the ***Alta X***, including during un-tethered operation. ### **Parts and Tools Required** * 1x ***Freefly Systems Alta X*** | Tool: Forceps * 1x ***EON800*** ***Serial Port Patch Panel for Alta X*** | Tool: *2mm Metric Hex Driver*

### **Goals** 1. Locate and expose the internal ***ALTA X FRX Cable*** and connect it to the ***EON800*** ***Serial Port Patch Panel**.* 2. SCREW and SECURE the ***EON800 Serial Port Patch Panel*** to the ***Alta X***. ### **Instructions** 1. The ***ALTA X FRX Cable*** is located in the front of the aircraft, next to the ***GPS/RTK Unit***. Use forceps to manoeuvre the cable out of the chassis for external access. 2. PLUG the ***ALTA X FRX Cable*** into the back of the ***Serial Port Patch Panel's*** receptacle.

3. Once the ***ALTA X FRX Cable*** is plugged into the back of the ***Serial Port Patch Panel***, SCREW and SECURE the ***EON800 Serial Port Patch Panel*** to the ***ALTA X.***

How to install the Serial Port Patch Panel to the Alta X

## Step B: Reset the Alta X Battery Tray (if required) The ***EON800 Air Power Unit (APU)*** has been designed to slot natively into the ***Alta X Battery Tray***, specifically when the ***Battery Tray*** is previously set for ***Alta X 12S Flight Packs***. Reset and lock the ***Alta X Battery Tray to its widest point***. If you were last flying alternative batteries to the ALTA X 12S Flight Packs, re-adjust the battery tray by loosening and adjusting the (8x) M3x6 SHCS fasteners and securing the two movable tray components. Ensure the fasteners are tightened after the trays have been adjusted. ### **Parts and Tools Required** * ***Alta X Battery Tray*** | Tool: 2.5mm Driver ### **Goals** * Expand and lock the ***Alta X Battery Tray*** to its widest point. This is the same width required to mount ***Alta X 12S Flight Packs.*** ### **Instructions** 1. EXPAND the ***Alta X Battery Tray*** (if required): LOOSEN the (8x) *M3x6 SHCS fasteners* on the ***Battery Tray*** with a *2.5mm Driver*. 2. PUSH both sides of the ***Alta X Battery Tray's*** movable components out and into its widest position. TIGHTEN the (8x) *M3x6 SHCS fasteners* on the ***Battery Tray***.

## Step C: Install the *EON800 Air Power Unit (*APU*) to the* ALTA X To prepare the ***ALTA X*** for the ***EON800 APU***, REMOVE the ***ALTA X*** ***Silicone Retention Battery Straps*** from the ***ALTA X Battery Tray*** and unpack the EON800 **APU** from its case. Ensure ***Alta X EON800*** ***APU*** ***Battery Output Leads*** are installed on the ***Alta X*** ***EON800 APU.***

## **Parts and Tools Required** * 1x XM2 *EON800 Air Power Unit for Alta X* * 1x *Freefly Systems Alta X UAS* | Tool: *2.5mm Metric Hex Driver* ### **Goals** 1. Install and secure the APU (Air Power Unit) to the Alta X using the *APU Push Pins*. 2. Connect cables between the APU and the ALTA X. ### **Instructions** 1. Position the **APU** with the fans facing towards the front of the **ALTA X** ( the GPS/RTK is at the front). 2. Align the (4x) **APU** Attachment Holes with (4x) *Alta X Battery Tray Studs.* 3. *Mount the* **APU** *to the* **ALTA X***.*

4. Remove the (*4x) Push Pins from the Air Unit and* insert them *in the hole formed between the APU Attachment Holes and the Battery Tray Studs.* 5. Insert the *Push Pins* into the mounting holes formed between the APU Attachment Holes and the Battery Tray Studs*.*

Insert the *Push Pins* into the Mounting Holes

6. Attach the APU *Battery Output Leads (XT90)* to the *Alta X Battery Ports*.
